' Be it known that 1, CHARLES B. SHERWOOD,

My invention is an improvement in signal lamps for motor vehicles, and has for its object to provide means in connection with the lamp or lamps of the 'vehicle, for signaling rearwardly the intention of the driver to stop or turn, wherein en auxiliary lamp is .mounted at the rear of the usual lamp an adapted to be ignited at will.

In the drawings:

Figure 1 is a side view or? improved lamp with parts in section.

Fig. 2 is a rear VlQVV'.

Fig. 3 is a diagrammatic view of the wirm I lhe present embodiment of the invention is shown in connection with a lamp havin a tapering or frustoconical oasinq 1, and provided at its large end with a white lens. A reflector 3 is arranged within the casing near the large end, and an incandescent globe 4 is arranged at the center of the reflector, the reflector acting" to throw therays of light outwardl through the lens. At the small end of t e easing a door 5 is arranged, the said door being hinged at 6 to the casing, and a spring latch? is provided for holding the door closed, the latch engaging a catch'S on the Basin-go '7 The door is rovided with a central opening, and the e go of the opening is ofiset inwardly to form a flange 9. A red lens 10 is seated on the flange, and a resilient split ring 11 is seated in the opening on the lens, to hold the same against the flange. An incandescent globe 12 extends inwardly from the side wall of the casing, the globe being at approximately the center of the lens 10, and a tapering reflector 13 is mounted upon the globe and between the same and the reflector 8Q The casino; 2 is provided at the reflector 13 with an internal annular groove 14, for receiving the edge of therefieetor 13,

and the reflector is held placeby its en- 4 gagement with the groove.

This globe 12 is designed be ignited at will by means of a push button or the like, which may be arranged in. any desired or convenient position. "Elie circuit 15f0r the globe 12 has interposed in the length thereof a source of supply 16, in the present instance a battery, and a push button 1'7, and it wili be evident that by manipulating the button the circuit may he closed whenever desired toigiuite the globe or to stop, he will press button, thus indie eating his intention to those following. As soon as the operator releases the button the circuit will he opened.
